CHANGELOG.md

1.2.4

• Collecting OSX disk capacity metrics

1.2.3

• Skipping mapped devices in disk collector

1.2.2

• Setting LC_ALL for disk
• More forgiving #linux? check

1.2.1

• Fix for OSX Memory to support 'unused' in addition to 'free'

1.2.0

Performance related:

• Using Dir#glob vs. Dir#foreach
• Using File#read vs. cat FILE.
• Removing commented out and unused elements from SysLite::ProcTable
• Removed method_missing logic in Processes::Process to access the ProcTableStruct
• Disk added caching logic via a @option[:ttl] to execute slow system calls at a lower interval (ex: ev 60 seconds)
• String#lines#to_a vs. String#split('\n') (faster)

1.1.1

• Handling Infinite and NaN Process CPU Usage.
• Case-insensitive process count grep, returning 1 processor vs. nil on rescue.

1.1.0

• sys/proctable is no longer a dependency in the gemspec.
• Linux systems with the /proc filesystem will return all process metrics
• other systems with sys/proctable installed will try to use sys/proctable, wnd will generally return a list of process names and counts (but no memory/cpu)
• all other systems: no process info returned

1.0.3

• Assuming 100 jiffies/second vs. reading from /proc/timer_list

1.0.2

• Also grouping under kthread (one d vs. 2 ds)

1.0.1

• Grouping kthreadd's children together under the comm "kthreadd"

0.1.0

• Optimization for collecting processes on Linux

0.0.9.0

• Reporting process memory in MB, not in page size.
• When determining process cpu usage, caching number of processors.

0.0.8.9

• Fix for top cpu-consuming processes in the process list

0.0.8.8

• Fix for LVM-mapped disk IO stats

0.0.8.5

• Mac per-process memory and per-process CPU reports 0s instead of throwing an exception (Mac only)

0.0.8.4

• Normalize load (last minute, etc) by number of CPUs. This keeps the metrics in sync with Scout's server load plugin.

0.0.8.3

• Fall back to assumption of 100 jiffies/sec if /proc/timer_list isn't available
